3,3′-Bisindoles are known to be important structural motifs found in bioactive natural products, pharmaceuticals, and functional materials. Herein, a novel indoxyl-based approach was established for the synthesis of unsymmetrical 3,3′-biindoles from indoles and indoxyls. This approach generated moderate to excellent yields of the desired products (24 examples, up to 98% yield). The present method features

A novel class of azaindole-indole coupled derivatives, their preparation methods, pharmaceutical compositions containing the same and the uses thereof. The common structural feature of these derivatives is that they are coupled by azaindole and indole bi-molecule at different positions, forming extended pi-conjugated systems. Such derivatives inhibited cell growth and proliferation by various mechanisms. The present compounds have improved solubility, increased bioavailability, and thus have enhanced drug actions, and reduced medical dosages and undesired responses.

A series of novel conformationally restricted N(1)-arylsulfonyl-3-aminoalkoxy indoles were designed and synthesized as 5-HT(6) receptor (5-HT(6)R) ligands. Many of the synthesized compounds have moderate in vitro-binding affinities at 5-HT(6)R. The lead compound 8b (% inhibition = 97.2 at 1 μM) from this series has good pharmacokinetic profile in male Wister rats and is active in animal model of cognition
